I can successfully access the specified URL on the server, but not in the container.
Then I found that the hosts inside and outside the mirror are different.

I use dify 1.3.0, docker compose up.

I found 6 similar threads that might be helpful:

1. New reason of Connection refused error - This discussion provides a solution for Docker containers not being able to access the host's port, suggesting changes to the docker-compose.yaml file.

2. Help Problem starting the project - This thread does not have a solution.

3. When using Docker Compose to deploy, Dify cannot access the API interface - The suggested solution involves configuring Docker network settings to ensure the container can communicate with the outside world.

4. I can't access http://localhost/install - This thread suggests verifying the .env file and checking Docker container statuses to resolve access issues.

5. Dify Incompatibility Between Local IP:Port and Domain-Based Access - The solution involves checking and updating the Nginx configuration to ensure proper routing to the service.

6. no route to host - This thread suggests replacing localhost with host.docker.internal in the service URL to resolve connectivity issues.

Unlike these, my dify cannot access the market, nor can it ask for the image URL I provided.
But I can do these outside docker.
